SAFETY-PIN.

I SPECIFICATION forming part of Letters Patent No. 628,598, dated July11, 1899.

- Application filed October 7,1898. erial No. 692,963. (No model.) 7

To (ZZZ whont it may concern.-

Be it'known that I, FREDERICK THOMAS CLARK, a citizen of the UnitedStates, and a resident of Somerville, county of Somerset, and State ofNew Jersey, have invented certain new and useful Improvements in Safety-Pin Locks, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof, in whichsimilar numerals of reference indicate corresponding parts.

My invention relates to safety-pins, and has for its object to provide asimple, inexpensive, and effective attachment thereto whereby the pointof the pin may be securely looked-in its sheath to avoid injury to theperson, so liable to occur from an accidentally-opened safetypin ofordinary form.

The invention will first be described and then will be particularlydefined in claims hereinafter set forth. I

In the drawings, Figure 1 is a side elevation of an open safety-pin withthe look attached thereto. Fig. 2 is a side view with the lock engagedwith the sheath and point of the closed pin, and Fig. 3 is across-sectional View taken on the line at 00 of Fig. 2.

The safety-pin proper has the usual form, and comprises an elastic wirehaving a body or bar portion 1 and a pointed end portion 2 connected bythe usual spring-coil 3, giving requisite elasticity for opening the pinautomatically when its point 4 is disengaged from the sheath 5, which isfixed t0 the end of the pinbar 1 opposite the coil 3.

My improvement in its preferred form comprises a movable latch plate orpart held to the pin bar or body and adapted to lock over the closedpin-point within the sheath.

This said latch-plate comprises a sheet-metal plate 6, having a loop 7,by which it is placed on the pin-bar 1, so as to slide along said barand bind upon or over the upper end 8 of the sheath 5, which is lappedupon and fixed to the bar 1. The oppositeor lower edge 9 of the lock ispreferably broadened or thickened, so as to fit between the oppositesidewalls of the sheath 5, and said part 9 is preferably provided with alongitudinal edge groove 10 more or less closely fitting over the pointof the closed pin.

In operation the pin is applied to one or more fabrics or parts thereofto be fastened and is then closed by slipping the pin-point at into thesheath' 5 in the usual manner,

whereupon the lock-plate 0 is slipped along the pin-bar 1 until its edge9 enters the sheath 5 and looks over the closed pin-point. The lowergrooved clamping edge of part 9 is preferably beveled to correspond withthe bevel of the opposing base of the sheath 5, and the lock-loop 7 isadapted to frictionally bind on the upper end 8 ofthe sheath, wherebysufficient friction is developed bythe latch acting on the pin-point andsheath to securely lock the safety-pin closed, and thereby preventdistressing accidents to children or oth-' ers to whose clothing the pinmay be adjusted. Having thus described my invention, what I claim asnew, and desire to secure by Letters Patent, is+

1. A safety-pin having a lock comprising a plate or part movable at oneedge along the pin-body and having at'its opposite edge a portionfitting laterally within the sheath and having an edge groove lookingover the closed pin-point, substantially as described.

2. A safety-pin having a bar or body portion 1 and a pointed end portion2 connected by spring-coil 3; and provided with a sheath 5, combinedwith a lock devicehaving a loop 7 loose on bar 1 and an opposite portion9 longitudinally beveled and grooved at its free edge and adapted toenter the sheath 5 and lock therein over the closed pin-point,substantially as described.

3. A safety-pin comprising a body portion with thepin-point and an endsheath, said pin having a lock comprising a plate or part provided atone edge with a loop loosely encircling and movable on the pin-body andof a diameter adapted for frictional contact around one portion of thepin-sheath, and having at its opposite edge a grooved portion ofsufficient thickness forfrictional contact against the inner side wallsof the free end of the pin-sheath, whereby the lock is retained againstdisplacement when in engagement with the sheath and serves to lock overthe closed pin-point, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 29th day of September, 1898.
